Title: Improvements in and relating to alternating current electric traction equipments including rectifiers
Inventor: BROWN JAMES KINGHORN
IPC: B60L9/12
Filed: 1957-06-04
Abstract: 890,494. Rectifying. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 2, 1958 [June 4, 1957], No. 17743/57. Class 38 (2). [Also in Group XXXVII] In normal operation of a traction equipment rectifiers R1-R4 are connected to an A.C' source through contactors C1-C4 and fullwave rectified current is accordingly supplied to series-connected motors M1, M2. In the event of a fault in the motor M1, or in either of the rectifiers R1, R2, contactors C1, C2 are operated to disconnect said motor and said rectifiers from the supply. The other motor M2 will thereafter be supplied with full-wave rectified current through rectifiers R3, R4 and an equalizing connection which is taken to a mid-tapping on a secondary winding of a main transformer T. If the motor M2 or either of the rectifiers R3, R4 should fail, then the contactors C3, C4 are operated so that only the motor M1 is supplied with current. As shown, tap-changing switches S1, S2 are used to vary the motor-voltage, but other transformer arrangements for controlling the motors are referred to, and in each case the equalizing-connection is taken to the effective mid-point of the supply system. The individual motors may be replaced by groups of motors, and the rectifiers mav be of the mercury arc or dry-plate types. Specifications 890,491 and 890,496 are referred to.

Filed: 1929-06-10
Abstract: 313,494. Janik, E. June 10, 1929. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 13, 1929]. Variable-speed gearing comprises a crank 3<1> of automatically variable throw which drives through suitable ratchets 12, 13. The crank-pin 3<1> is carried by a block 3, Fig. 1, which moves transversely in a frame 2 fast on the driving- shaft 1. The throw of the crank is varied by bringing non-rotary frictions discs 26, 27 alternatively into engagement with a friction pin 28 fast on a screw 42, which moves bodily inwards and outwards. The discs 26, 27 and pinion 28 are coned as shown. A connecting-rod 4 connects pin 3<1> to a slider 5 which reciprocates in fixed guides 7, Fig. 2. The slider 5 is connected by links 10, 11 to ratchets indicated at 12, 13 which drive in one direction a loose drum 16 connected by springs 23 to a boss 19 fast on driven shaft 22. Upon the boss 19 are governor shoes 24 which move radially and act through links 18 to slide a sleeve 17 upon the drum 16. The sliding of sleeve 17 is communicated by means 25 to the discs 26, 27 which move from side to side to change the direction in or out in which the crank 3<1> is to be moved to maintain the speed of shaft 22 constant.

Abstract: 630,810. Centrifugal machine brakes. WESTERN STATES MACHINE CO. July 8, 1947, No. 18012. Convention date, Aug. 21, 1942. [Class 23] [Also in Groups XXIV, XXIX, XXXIV] A handbrake for a high-speed heavy centrifugal machine acts on a drum 104 disposed between the motor M and the basket 100. The brake shoes 106, 108 are applied by a pair of cylinders 118 supplied with fluid pressure from a cut-off valve 122 and regulating valve device 132L The operation of the valve device 132 is such as to produce a gradual increase of the braking force as the speed of the machine falls, so that the braking is kept at a maximum without exceeding the heat dissipation capacity of the friction elements. The action of the device 132 may be similarly applied to the elements of a clutch for accelerating the machine.

Patent GB-785934-A (GB)
Title: Fertilizer materials
Inventor: DEE THOMAS PRIDE
IPC: C05B19/00
Filed: 1954-06-19
Abstract: The caking of granular phosphorus containing fertilizer materials is prevented by spraying the granules with a dilute aqueous solution of an alkali metal lauryl sulphate, preferably sodium lauryl sulphate in an amount corresponding to 1 to 3 lbs. per ton.  The spraying, which may be effected with a 3 to 10 per cent lauryl sulphate solution, may be effected before or after cooling the granulated fertilizer, for example while the fertilizer is carried on a conveyer belt or while it is falling as a stream.  According to an example a granular fertilizer containing superphosphate, ammonium sulphate and potassium chloride at a temperature of 50 DEG  to 60 DEG C. was sprayed with a 7,5 per cent aqueous solution of sodium lauryl sulphate at the same temperature, in an amount corresponding to 0,15 per cent sodium lauryl sulphate based on the fertilizer weight.  The resulting granular product when cooled had a moisture content of 2 per cent and did not cake on storing.

Abstract: 224,577. Maupied, E. E. July 13, 1923. Spray carburettors. - Within the casing s, which is provided with a number of radial air inlets l, is a tubular member r, with corresponding inlets l<1> adapted to be rotated and' at the same time raised and lowered by a handle o moving in a cam-shaped slot in the wall of the casing. The member r carries a fuel needle p adapted, in the lowest position of the member r, to close the outlet of the fuel nozzle g which is arranged in the line of the mixture flow. The fuel flow is regulated by a screwed rod v having a number of bores of different diameters which, by rotating the rod, can be brought into alignment with the fuel passage. A nozzle m, Fig. 3, for injecting steam may be provided. With the member r in the position shown in Fig. 1, the air and fuel ports are fully open. By moving the handle o anti-clockwise the air ports are closed and the member is lowered to restrict the fuel supply, Fig. 3. When in its lowest position, further rotation of the handle o in the same direction along the horizontal part of the cam slot, again opens up the air ports, the fuel port being still closed. At starting, fuel may be supplied from an elevated auxiliary reservoir.

Abstract: 1397539 Blind riveting AVDEL Ltd 26 May 1972 [28 May 1971] 18177/71 Heading B3U Blind riveting apparatus comprises a mandrel 12 having a stem 14 and head 16, holding means 18, 20 for holding the mandrel and providing an abutment 22, 24 for supporting a rivet in a rivet setting operation, axially reciprocable gripping means 26, 28 for gripping the mandrel at a position rearwardly of the holding means and for moving the mandrel axially relative to the abutment to pull the head 16 through a tubular rivet supported by the abutment, the holding means and gripping means each being operable to release the mandrel when the other of the holding means and gripping means is holding the mandrel, to allow a rivet to move forwardly along the mandrel, and means 32 for forwardly advancing a rivet supplied to the rearward end of the mandrel. With the mandrel in its rearward position as shown in Fig. 1, the gripping jaws 26, 28 are opened to allow a rivet 34 to be moved forwardly along the mandrel by a blast of air from jet 32 until the rivet abuts the rearward side of closed nose jaws 18, 20. The jaws 26, 28 are closed to grip the mandrel and then moved forwardly carrying the mandrel to its forward position. At the start of the forward movement of the jaws 26, 28, the jaws 18, 20 are opened to allow the rivet 34 to be driven against the mandrel head by the sustained blast of air and then closed to provide the abutment for the rivet 34, Fig. 4. The rivet 34 is then positioned in a workpiece so that on rearward movement of jaws 26, 28 the mandrel is pulled rearwardly to set the rivet 34. As the mandrel moves rearwardly the rear end of the mandrel stem enters the bore of a further rivet 36. The apparatus is thus returned to the position shown in Fig. 1, so that the sequence of operations previously described may be repeated.
